This invention pertains to improvements in presses and relates more particularlyto that type such as shown and described in Letters Patent .to Anderson ,No. 31,737 6 dated.June 23,1903. 1 i. As will .be seen upon'referenceto that patent ;'the press,stated generally, may. be said to comprise a shell composed of a series of bars arranged in,cilfcular. series with the inner ,edges'slightly spaced apart and held in'such relation by j aseriesfof transversely arranged sustaining members. Extending through the shellis a shaft having mounted thereon and for rotation there- 16 with a series of separated pressing worms, the shaftat theintakeend being surrounded by a quillor sleeve having a plurality of werms formed thereon, for. thefpurpose of feeding the material inwardly of the press and likewise imparting an initial pressure thereto. Means is provided asin the present case, toydrive the quill at ,a. higher speed than thatiinpartedtothesha ft. Q 7 While the press, .as 'above' outlined, has

2 been highly eflicient in extended use, the last or initial compression flight or worm has been founjdjzte wcar'away, faster than the others, including the main. compression worm, necessitating replacement, of the quill as a whole. y Added-to the :labor. cost ,ofwithdrawal and replacement; thesubstitution of anew quill-is quite anitemof cost t w: L j v The present case hasfor its object the production of; a quill in which the Wear is substantially equalized throughout,v Incidentally the new construction and formation produces .a more effective feeding of thema terials and further, does away with the .for mation of, an oil massfatthe intake end of the press, a condition which hasheretofore existed when certain'materials were undergoing treatment.

In the annexedjdrawings;

Figure 1 is a longitudinal verticalsectional view of a press of .the type above outlined illustrating the new quill formation, and

Figure 2 is a side elevation of the quill.

- In said drawings, 1 denotes the shell which may be of any approved formation, supported by a suitable frame 2, a portion only of which is shown. The shell elements are held in position by transverse members between them an inclinedfsection 17. The

tion 18 which isthreaded into a driving eleor heavy plates 3, arranged to either side of the elements a'ndthese in turn are secured in position by. longitudinally arranged pressure'bars /l,the bars upon opposite sidesv of the; press being drawn together by heavy bolts 5,1shown-inseotion in Figure 1.

Located at the head or intake end of the press'fis feed? hopper 6 and-extending therethrough and through the shell is a shaft 7 driven anysuitable -mechanism (not'sh0wn)' Said shaft carries a series of separated worims, designated by 8 which wo'rms as in the patent above. referred to, tendto 'compress the material and advance it toward the discharge endvof the press where the compressed material passes over a sleeve Qand is forced against av cone-shaped member 10 which tends to disrupt the cake which is forced, outwardly by the worms.

Bar's llcarrying knives 12 which extend inwardly between the worms, tend to prevent rotation of thematerial within the shell and thus permit the worms tobuild up pressure against .the material} passing through the press. v

" The quill which is located atrthe intake end-of the machine is shown in detail in FigureQ. It is of tubular form and is held outof 1 contact ,withthe shaft by a sleeve 13,

of bronze or tlie like, located adjacent a collar 14 formed upon the shaft 7 @The quill may be said to comprise. an'in-v feed section 15 of, av diameter somewhat smaller than the opposite end denoted by 16 whichisections or portions have arranged inner end of the quillis', as will beseen upon. reference to Figure 1, 'counterbored to .receive the sleeve 13. The opposite end. ofthe quill is provided with a'threaded sec ment "19 which receives its motion from any suitable mechanism (not shown). V

.In practice thelquill and shaft will be driven at different speeds, the speed ofv the quill being substantially 66% faster than that of the shaft 7 and consequently faster than that of the pressing worms carried by the shaft. 7

The quill, at its intake end, isprovided with a worm or flight 20 which underlies the hopper 6 and extends at its inner end slightly beyond the hopper toward the intake end of the shell. A compressing worm or flight 21 is arranged next to the feeding flight 20 and stops short of the inclined face 11 17 of the quill. A pressing worm 22 is formed upon the enlarged section 16 and tends to force the material forwardly through the shell as well as subjecting it to compression.

In presses of the type herein described and as heretofore used, the inclined face on the quill, where such face was used, was located intermediate the first pressing worm, carried by the shaft, and the end worm of the quill, or, in another form, this incline was located well forward or immediately adjacent to the entrance from the hopper to the press. It has been found in actual practice that by locating the inclined face 17 in the position shown in the present case, that is to say, between the pressing worm 22 and the pressing worm 21 carried by the quill, that the quill and the worms carried thereby wear away evenly. Furthermore, it has been found that while the old type of worm, first described, takes the materialinto the barrel or shell of the press equally as well as the new type, or that herein set forth, does,

there has been an excessive wear on its end due to the reduction in area, at the point noted, while the second old form, above referred to, does not feed the materials into the barrel readily due to reduction of area at the entrance of the barrel or shell. This latter form of feeding worm or quill moreover, will not Work on some materials at all for this reason. It has been found with the new form that non-fibrous materials such as roasted peanuts, cocoa beans, etc. willbe fed into the expeller or press better than with either of the old forms; the first old form tending to break the material up into an oilypulp, whereas the second oldform, while it may not produce this pulpy mass, does ,not feed the material as efficiently to the press as does the form herein set forth and claimed.

As above noted, the present form of quill. shows an even wear throughout whereas with'the older forms the end or inner flight was found to wear away even before the pressing worms are worn out. With the older form wherein the incline is just. in

advance of the feeding flight and adjacent the hopper, difficulty is experienced in forcing the material up such inclined face. With the other older construction the incline is located at the inner end of the quill and the 1 speed.

quill diameter is smaller than that of the pressing worms--hence the innermost flight of the quill has considerably more work imposed upon it owing to the fact thatsaid flight has to press the materialinto a smaller area and is also.operating'under high As will be seen upon reference to Figure 1, the external diameter of the section 16 is substantially the same as that of the hubs or elements from which the pressing worms 8 extend outwardly.

Having thus what I claim is:

1. In a press of the character specified,

described my invention the combination of a shell; a feed hopper located atone end thereof; a shaft extendlng through the hopper and the shell; a series of spaced pressmg worms mounted upon the shaft adjacent the discharge end of.

the press and rotatable therewith; and a quill encircling the shaft adjacent the intake end of thepress, said quill having a feed flight formed upon its outer faceadjacent the hopper, then a combined feeding and pressing fllght, and, at its inner end,

which latter is enlarged in diameter over the remainder of the quill, a presslng worm or flight, said feeding flight, feeding and pressing flight, and pressing worm being likewise spaced apart.

2. In a press of the character specified, the combination of a shell; a feed hopper located at one end thereof; a shaft extending through the hopper and theshell; a series of spaced pressing worms mounted upon the shaft adjacent the discharge end of the press and rotatable therewith; a quill encircling'the shaft adjacent the intake end of the press, said quill at its inner end being enlarged in external vdiameter and con nected to the forward portion byan inclined face; a feed worm formed upon the exterior of the quill adjacent the intake end of the.

press; a combined feeding and pressing wormlocated between the last named flight or worm and the inclined face, aforesaid; and a pressing worm mounted upon the quill at its inner end where its external diameter is enlarged. said feeding flight, feed ing and pressing flight, and pressing worm being likewise spaced apart.

In testimony whereof I have name to this specification.
